Ann: Drilling Commences at TAO-1 Well, page-65

Decrisper, you are correct .8 x 1 x 1 x 1 x 1 = 80%

When you think about it flipping a coin is 50% COS, if you call it twice in a row and you are correct that's another 50%

So .5 x .5 = .25 or 25% COS

So a 29% COS is a better chance of calling a coin correctly 2 times in a row.

I just flipped a coin and called heads, I was right so I'm in until the announcement.

The attraction of this is not so much that its a 29% COS, its that the reward far exceeds the odds of success as others have posted.
